Abstract

The paper deals with a condition-based maintenance policy for a two-component system with dependencies. Two kinds of dependency are investigated. The first is state dependence whereby the deterioration speed of each component depends not only on its own state (deterioration level) but also on the state of the other. The second is economic dependence whereby combining maintenance activities is cheaper than performing maintenance on components separately. To select a component/group of components to be preventively maintained, adaptive preventive maintenance and opportunistic maintenance rules are proposed. A cost model is developed to find the optimal value of decision parameters. A numerical example is introduced to illustrate the use and the advantages of the proposed approach in the maintenance optimization framework.
